This polished, solid brass sundial compass makes a perfect gift to adorn an executive's desk, or a functional nautical accessory for a book shelf. It measures 5" tall x 2 3/8" tall when collapsed. The magnetic brass compass allows you to orient to North while the needle lock protects the jeweled compass bearing during transit. The bubble level allows you to properly set the compass before setting curved latitude scale. The curved scale is used to set your local latitude angle allowing the gnomon to cast the shadow at local time. Give a sundial compass gift that will be proudly displayed for years to come.
